TO'ALL WHOM IT MAY CONCERN:

Be it known that I, JAMEs D. SARVEN, of Columbia, inthe county of-Maury, and State of Tennessee, have invented a new and improved Elastic Bearing for Body-Supporting Irons for Carriages; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, and which- Figure 1 is a longitudinal vertical section of my invention, showing the supporting-iron in position, and

Figure 2 is a top view of the same. 7 v

This invention is an improvement upon a device previously patented vby the same inventor, and consists in confining the head of the supporting-iron in the box by means of vertical grooves in th'e side of the head,'into which fit corresponding projections from the inner sides of thebox, or by means of a bolt passing vertically through the box.

Similar letters of reference indicate corresponding parts in the drawings. g

In the drawings, A represents one of the cross-bars which support the body of the carriage, and B represents the box near its extremity, in which are enclosed the elastic bearing 0 and the head'ofthe supporting-iron D. This invention is confined to a new and improved meansof fastening the head of said iron .in the box' B, so that while the iron can workup anddown'freely it cannot escape from the box. To accomplish this purpose, I make a vertical groove or gain, e e, on each side of the head of the iron, D, and in connection therewith I construct the end walls of the box B with a vertical projection, e, on their inner side, extending into and par tially filling the groove e. The top of the box B is made detachable; the lower cushion of'the elastic bearing is placed in the box; the supporting-iron is then inserted upon it; the upper cushion is placed upon'the head of the iron; the top of the box is next fastened on; and no amount of force can then withdraw the iron, D, from the box. The grooves being vertical, the iron plays i'reely up and down on the cushions. The projections are made to fit loosely into the grooves, in order that the irons may work easily.

In lieu of this construction, or in conjunction with it, I may drill a vertical hole through the centre of the box, bearings, and iron head, and confine the iron in place by means of a bolt, G. In this case the bolt should be made to fit loosely in the hole through the iron head, but may be tightly fitted to the box and cushions, and may be keyed or otherwise fastened, to prevent it'bcing worked out.

The box itself may be attached to the crossbar by any suitable means. In the drawings I have shown a simple and elleotive method of fastening it, consistingof a thin strap or hoop of iron or brass, fitting over the cover of the box, and screwed down through flanges at its bottom to the crossbar, thus serving the double purpose of securing the cover to the box and the box to the cross-bar. The box may be cast in one picceor two, and either with or without a bottom. If cast without a bottom, the top may be cast solid with the box.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

lhe method of fastening the iron head D in the box l3, asabove described, by means of vertical groovese e in the side of the head, in connection with vertical projections in the box, or by means of a vertical bolt, G, passing through the centre of the box, substantially asand i'or the purpose specified.
